Abstract :
An improved method of calculation is described which the eddy current reaction and the variable permeability of the solid pole are taken into account. At no-load, the saturation of the stator teeth is fully considered and shows that tooth-ripple harmonics are increased by it. On load, the stator MMF harmonics of integral-slot windings are determined and added with due regard of their phase shift.
